neo key or neo mod
 

What are the difference? I heard that with the neo key you still have to patch the game. Is this true? Is the neo mod better that the neo key?

If you dont mind patching the EA titles then the neo key works fine. As far as which is better, the neo key or the neo 2.2 chip, i would have to say the chip. Most people dont wont to be bothered with patching so it's a little easier to get the games to load using the chip.
